1Device tree configuration for the I2C Interrupt Controller on the AST24XX and
2AST25XX SoCs.
3
4Required Properties:
5- #address-cells	: should be 1
6- #size-cells 		: should be 1
7- #interrupt-cells 	: should be 1
8- compatible 		: should be "aspeed,ast2400-i2c-ic"
9			  or "aspeed,ast2500-i2c-ic"
10- reg			: address start and range of controller
11- interrupts		: interrupt number
12- interrupt-controller	: denotes that the controller receives and fires
13			  new interrupts for child busses
